Research direction

Start in GithubClient.java at getLatestAzureMcpRelease, especially line 103 where the GithubRelease list is deserialized, then review executeWithRetry at line 64. Compare the GitHub response shape with the expected ArrayList< GithubRelease > value and verify the corrected behavior against the reported IntelliJ Azure MCP initialization failure.
